SPRING-BED-Borrom ,misere Application led March 8, 19217.l Serial No. 450,656.`

' of the borough of Brooklyn, county of Kings,

city and State of New York, and FRANK KoroinNsnr, a citizen of Poland, and a residentof Jersey City, county of Hudson, and State of New Je1scy,'have invented certain new and useful Improvements in Spring- Bed-Bottom Fabrics, of which the following is a specification. i

vThe object of our invention is to attain 'a simple, cheap but effective structureof spring bed-bottom fabric, the parts of which coupling up not only with said end members may be assembled with facility, and without the-aid of specially skilled labor. By our construction and arrangement of parts, re-

placements may be easily made if necessary g' and the component parts of the structure separated and manipulated for cleaning, etc., and then re-assembled manually for use by persons of ordinary ability. i

y To this end the invention consists in the specific combination, construction and arrangement of parts and elements described and claimed,-a distinctive feature being the conguration of the continuous interlocking loop hook sections ashereinafter fully set fort-h.

In the accompanying drawings,

Figure 1 is a top view of a spring bed bottom made in accordance with our invention, broken away centrally;

Fig. 2 is a side elevation of a portion thereof; i

Fig. 3 is a detail view of one of our continuous interlocking hook sections; and y Fig. 4 is a detail view illustrating the interlocking of the parts. y

IVe use a metallic supporting frame of ordinary and well known construction, consisting of the end members e, e, angular in cross section, to which are rigidly attached the bracket socket pieces b, b, in which the ends of the tubular` side members a, a are mounted and supported in a manner well knownin the art.

S are the usual spiral springs connected with the end members e, of the frame, being formed with loop hooks s, which engage with the holes e', formed for the purpose 1n said end members e. Both ends of said spiral springs S are formed with loop hooks .9, for

but also with the end sections of our interlocking loop hook sections C of which the bed bottom fabric is constituted.

Each interlocking loop hook section C is formed of a single piece of metallic wire of suitable thickness and tenacity, bent to form a series of elongate loops c, connected by transverse basic li gements c', the basic ends of the loops @between the ligaments c being bent into the form of duplex hooks c2 in a plane at right angles to that 0f the elongated loops and adapted for insertion in the bights cX of the aforesaid elongate loops c of the next adjacent loop hook section C, as shown in the drawings, particularly in Fig. 4 thereof.

As will be seen from Fig. 4, the bights c are interlocked in the duplex hooks c, by reason of the later being given such a twist as to throw them out of the plane of the ligaments c', the loop portions of the hooks being seated in the seats thus formed, and thus the sections are held against undue movement.

The bights e", of one of our continuous interlocking loop sections C are inserted in the loop hooks s, of the coiled springs S at one end of the frame, and the duplex hooks c2 may also be coupled with the spring loop hooks s atthe other end of the frame, as shown in Fig. l.

Our interlocking loop hook sections C are made of a length equal to the width of bed bottomrequircd, and any desired or suitable number of these sections C are coupled together to afford the requisite length of bed bottom. v

Our continuous one-piece interlocking loop lhook sections C are of simple construction,

and if made of metallic wire of suitable diameter, the unitary structure vthus attained insures strength and durability, while affording ease of manipulation in assembling of parts. Furthermore, the connecting means are not complex as compared with the prior state of the art, and hence more sanitary, as affording less opportunity yfor the accumulation of dirt, and the harboring of insects, etc. In this connectionV the facility with which the Vparts may be disconnected for purposes of inspection and cleaning is of practical importance, as well as thevfact that the replacement of parts may be readily effected in case of necessity.

By the term bed bottom fabric we mean to designate the interlocking connectedistruc- .Patented Mar. 1 4, 1922.'
